Análise de frutos e nozes de cultivares de nogueira-macadâmia

The production of the macadamia walnut is measured in "nut in peel" (peel and almond). The cultivar that have higher caliber has greater commercial value. The objective of the present research was to analysis of fruits and nuts of 22 cultivars of macadamia walnut. The cultivars used were: 'Africa', 'Beaumont' (695), 'Cannon', 'C160', 'Doroti', 'Edson', 'Flor Rosa', 'HAES 722', 'HAES 814', 'HAES 816', 'HAES 842', 'HAES 849', 'IAC Campinas-B', 'IAC 9-20', 'IAC 9-20X', 'IAC 4-12B', 'Kau' ('HAES 344'), 'Keauhou' ('HAES 246'), 'Keaumi' ('IAC 4-20'), 'Mauka' ('HAES 741'), 'Pahala' ('HAES 788') and '791 Fuji'. It was determined the dimensions (length and diameter) and the fresh weight of the carpelo, peel and almond, besides the fresh weight of the "nut in peel" (peel and almond), besides TR (relationship among the weight of the nut in peel and the weight of the rescued almonds). The cultivars presented differences as the dimensions of the fruits. The cultivar 'Edson' presented fruits and nuts with larger dimensions and weight. The cultivars 'Pahala', 'Beaumont', 'IAC 9-20X' and 'Keaumi' presented TR lower than 30%.
